Criteria for Diagnoses of Flagellate Fungi

Abstract

For most of the organisms discussed here, the normal method of asexual reproduction is by spores originating from a sporangium. Exogenously produced conidia or chlamydospores are either not known or of minor significance. In eucarpic organisms with hyphae, the sporangia are separated from the assimilative mycelia by septa or plugs. For holocarpic organisms, in which all nucleated protoplasm is utilized in spore production, the definition of a sporangium becomes difficult: at maturity, the assimilative thallus is converted into a sporangium, frequently with little morphological modification other than the formation of an exit tube and dehiscence papilla.
